Subject: s390/crypto: add cpu feature modaliases for crypto modules
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d05377c12ae2ac88e747a28ae1e23f556d549592;p=linux-beck.git

s390/crypto: add cpu feature modaliases for crypto modules

Use the module_cpu_feature_match() module init function to add an
module alias based on required CPU features.   The modules are
automatically loaded on hardware that supports the required CPU features.
